1981 Walter D. Koenig Melanerpes famicivorus Lower Haystack Hastings Reservation 11 May Watched the granary hole; Ron is on the hillside while Janet is over at the roost hole. This went on through the morning (see compilation on back) during which time 9524 laid again and 9523 came close to entering but never did. We proceeded to put a complete watch on the hole, but despite our efforts we missed the egg-tossing, which did in fact occur as the egg was gone when Ron checked the hole in the evening. In any case, the nest is again empty. 12 May Watched the hole again from 505-800 (see back); 9524 again laid but this time we saw it all: 9523 tossed the egg, following which Ron watched it get eaten by the group members (I managed to find the egg stuck up in the tree just after it was removed [it was still intact]; I measured it and took some pictures of it and then put it back. Ron then sat with the camera and watched it get devoured.) A success'. Meanwhile, Ron checked the other holes to confirm that 9523 isn't laying somewhere else. The egg laid by 9524 in the roost hole on the 10th is still there. 13 May Watched from 520-910; both birds laid simultaneously today so it's probably all over. 9523's (presumed) egg was pretty small so it's possible that she might bag them both; Ron stayed on for a while longer just in case. 520. watching. 614. 9524 enters. 625. 6461 here, 9523 also. 631. 9524, then 9523 leave together. 626. 9523 enters.
